Tips:

1. Currently, the Double chainring products in production do not support small chainrign with small cog gears. In this case, using the chain will scrape the upper chain rivets of the larger Chainring ​ ​2. The BCD110RB series Double chainring s support R7000/R8000/R9100 cranks, but the position and size of the claws of these cranks are different. The Chainring design is aligned with the claws of the R8000 cranks. Therefore, the positions of the other crank claws are not aligned. ​ ​3. The product must be installed and used in one set, and cannot be used interchangeably with any other brand, and cannot be provided as repair parts for other brand products. ​For example: the products BCD110RB-5236 and BCD110RB5034 are dual-disk, which can only be used in 52T+36T, and do not support mixed use such as 50T+36T or 52T+34T.
